The Pennsylvania Turnpike Commission advises motorists traveling southbound on the Northeastern Extension (Interstate 476) to be prepared for slow-moving or stopped traffic approaching the Mid-County Interchange (Exit #20) due to the Express E-ZPass lanes being closed at 9:30 a.m. on Sept. 8 for routine maintenance.

Conventional E-ZPass and cash lanes will remain open for traffic exiting the Turnpike system to continue southbound on the Blue Route to I-76 and I-95. Customers exiting the Northeastern Extension at the ramp to enter I-276 westbound may also experience delays.

The closure will allow the Turnpike to perform routine maintenance on the electronic tolling equipment. The southbound Express E-ZPass Lanes will be reopened to traffic by 3 p.m.

If the Turnpike's Highway Advisory Radio is activated, as indicated by yellow flashing lights, please tune to Radio 1640 AM for updates. For emergencies, please dial *11 on your mobile phone.

Weather could delay or cancel this closure. Turnpike travelers can get up-to-date traffic alerts by calling 866-976-TRIP (8747) or visiting the live Travel Conditions Map online at www.paturnpike.com/webmap.
